[0010] The utility model discloses the following beneficial effects:

[0011] 1. When the second handwheel is turned, after being driven by the worm gear reducer, one screw rotates. Under the transmission of the synchronous toothed belt, the two screws rotate synchronously. Thus, the screws and the threaded sleeve cooperate with each other, causing the lifting plate to move up or down. At this time, the height of the support plate used to support the three-box cabinet changes, realizing the adjustment of the working height and alleviating the sub-health caused by maintaining one posture for a long time during work.

[0012] 2. When the first handwheel is turned, it drives the stud to rotate. The stud drives the slide to slide along the horizontal part of the second U-shaped frame. At this time, the slide and the trapezoidal block cooperate with each other, which changes the tilt angle of the pallet. At the same time, the length of the elastic rope is stretched and changes, which causes the pallet to rotate around the hinge, thus changing the tilt angle of the pallet and realizing the adjustment of the working angle, which helps to improve work efficiency.

[0013] 3. When the pallet is tilted, adjust the height of the movable plate as needed so that the vertical rod slides along the vertical hole. When the movable plate moves to an area where the three-box cabinet does not affect the wiring, use the positioning screws to limit the relative position of the vertical rod and the L-shaped plate. In this way, the movable plate and the pallet cooperate with each other to limit the tilting state of the three-box cabinet on the pallet. Attached Figure Description
